eCPM or Effective Cost Per Mille is one of the most important revenue metrics publishers need to track. In this post, we’ll help you avoid any confusion by taking a closer look at its meaning, how to calculate it, how to optimize it, and answer other questions you may have.
eCPM, an abbreviation for Effective Cost Per Mille, represents the estimated earnings of an ad per 1,000 impressions. Essentially, it serves as a bridge between CPM (Cost Per Mille) and CPC (Cost Per Click) advertising, offering a comprehensive measure that aids publishers in evaluating the performance of their ads. It is used on many platforms that monetize through display ads which can include desktop, mobile, in-app, and video.
The higher the eCPM, the more money publishers are earning from their ad units. So what is eCPM and how do you calculate it?
eCPM Formula = Total Ad Earnings / Impressions x 1000
For instance, if an ad generates $100 from 50,000 impressions, the eCPM would be:
eCPM = 100/50,000 * 1,000 = $2
The metric encapsulates:
This question gets typically asked by people who don’t understand what eCPM is in the first place. The previous sections should have cleared up some confusion. Here is a simple explanation to further demonstrate its use.
Let’s say you’re a publisher and your site is generating 100,000 impressions per day. You’re testing different revenue models and want to focus on monetizing via display ads.
You set up Google Ad Manager and place the ad units on your website. After a week’s time in your revenue dashboard, you calculate an eCPM of $4.
This means that you used the formula:
eCPM = Total Ad Earnings / Impressions x 1000
Then plug in your Total Ad Earnings ($400) and Impressions (100,000)
=($400 / 100,000) x 1000
eCPM = $4
So for the 100,000 impressions you generate per day advertisers are paying out $400 to you. So for every 1,000 impressions you generate, you earn $4. If your website traffic stays constant for the next 30 days at 100,000 impressions per day, you’ll make $12,000 in ad revenues at a $4 ad eCPM.
Here’s that broken down at a monthly basis for you:
eCPM = Total Ad Earnings / Impressions x 1000
Then plug in your Total Ad Earnings ($12,000) and Impressions (3,000,000)
= ($12,000 / 3,000,000) x 1000
eCPM = $4
Since eCPM can be used on so many platforms, each with a different set of users, rules, ad networks, and ad servers, there is no one size fits all solution.
To improve your eCPM means that you will need to optimize your ad monetization strategy, whether it’s for display advertising via desktop or through your mobile app.

Here our answer will be very similar to the section on increasing your ad revenues above. There can be many reasons for low eCPMs or poor ad earnings. This can include displaying ads from an ad network that does not correctly support your traffic geography or utilizing a poor ad network.
Or, not having enough advertiser competition for your traffic. Also, you might have a slow website, a bad ad layout or you’re not utilizing the correct ad units. It could even mean having some pages banned from your ad network and not displaying ads correctly.
eCPMs differ a lot depending on where the ad is placed (above the fold or below the fold), your traffic geography (tier one such US, UK tend to be higher), seasonality, site speed, user engagement, and even your niche.
In general for a publisher monetizing with display ads, one can expect an eCPM range of $4 – $10.
Enhancing eCPM is pivotal for publishers looking to maximize their ad revenue. Here are some salient strategies:
Content is king. High-quality, engaging content attracts more visitors and keeps them on the page longer, boosting ad impressions and eCPM.
Ads positioned strategically, especially near engaging content, have higher chances of being viewed and clicked, positively impacting eCPM.
With the myriad of devices available today, it’s imperative to use responsive ad units to ensure ads display correctly across different screens, leading to better engagement and higher eCPM.
Rich media ads, like video or interactive banners, typically have higher engagement rates than standard display ads, potentially driving up eCPM.
Regularly analyzing performance metrics can reveal patterns. By capitalizing on these insights, publishers can refine their strategies, optimizing content and ad placements for better eCPM.
In the quest for higher eCPM, publishers often encounter certain challenges:
eCPM can fluctuate based on several factors like ad demand, user location, or time of year. It’s essential to constantly monitor and adjust strategies to maintain consistent growth.
With users increasingly employing ad blockers, it’s crucial to diversify ad formats, focusing on non-intrusive ads and encouraging users to whitelist your site.
The digital ad space is competitive. Continuously innovating and adapting to industry trends is the key to staying ahead and maintaining a high eCPM.
